LESCO, K-Electric, FESCO and IESCO Bill Slabs Compared
Compare what is common—and what must be checked separately—when reading residential electricity tariffs across major Pakistan providers.
Residential bills from LESCO, FESCO and IESCO generally follow federally notified tariff structures for distribution companies, while K-Electric has its own determinations and schedules. The provider name alone does not identify your rate: sanctioned load, protected status, consumption history, time-of-use metering, billing month and later adjustments all matter.
What to remember
- ✓ Compare the same consumer category and billing month—not just the provider logo.
- ✓ Separate base energy charges from taxes, fuel adjustments, quarterly adjustments and arrears.
- ✓ Use the official tariff schedule and your actual bill as the final reference.
Begin with the connection, not the company
A useful comparison starts with the consumer category printed on the bill. Two homes served by the same company can face different treatment because one has protected status, a different sanctioned load, a time-of-use meter or a billing history that places it in another group. Comparing the final rupees per unit without matching these details produces a misleading result.
LESCO, FESCO and IESCO are distribution companies operating in different service territories. K-Electric is an integrated utility serving Karachi and nearby areas. Their bills look broadly familiar because each must communicate units, tariff components and government charges, but the applicable notifications and adjustment periods may not be identical.
What is normally comparable
The core measurement is kilowatt-hours consumed during the billing period. A bill then applies the relevant residential tariff treatment and adds other items. This common structure lets you compare energy use, but it does not mean every displayed charge will be the same in Lahore, Faisalabad, Islamabad and Karachi during the same calendar month.
For a fair comparison, record units, billing days, meter type, sanctioned load, category code, protected or non-protected status, previous balance and every adjustment line. If any of those fields differ, explain the difference before attributing the result to the provider.
- Units and meter readings
- Billing period and days
- Category and load
- Protected status or time-of-use status
- Taxes, adjustments, arrears and credits
Why the effective rate changes
Effective rate means the total payable amount divided by units. It rises when fixed charges or one-off adjustments are spread over low consumption, and it can jump when usage or history changes the tariff treatment. It is therefore a description of one bill, not a reusable tariff.
Fuel-cost and quarterly adjustments can refer to earlier periods even though they appear on the current invoice. Taxes can depend on government rules and consumer details. Arrears, late-payment surcharge, instalments or a credit from a corrected reading belong to the account history rather than the current month's electricity consumption.
How to read each provider's bill
Find the category, current and previous readings, units, billing month and due date first. Then copy the energy charge and each additional line into separate rows. Do not combine an adjustment with the base tariff merely because both are calculated per unit.
Use the provider's own bill portal or helpline to verify a duplicate bill or correction. For tariff research, use NEPRA determinations and notifications. A social-media image of a slab table may be outdated, may omit a category, or may describe the calculation incorrectly.
A sensible household comparison
If you are comparing a move between cities, start with the same monthly usage profile rather than last month's payable totals. Model summer and winter separately, include the likely meter category and keep non-energy charges editable. This produces a planning range rather than a false promise.
If you are investigating an unexpectedly high bill, reproduce the account's own bill before comparing providers. Check reading type, billing days, accumulated units, previous balance and status. A meter-reading or history issue cannot be diagnosed from a national slab chart alone.
When to ask for correction
Contact the relevant provider when the meter reading, category, load, account history or payment record appears wrong. Keep photographs of the meter, paid receipts and copies of bills. Use the provider's complaint process and retain the complaint number.
A calculator can reveal that a bill is unusual, but it cannot determine whether the meter or official assessment is wrong. Escalation should be based on documented account facts and the current regulatory complaint process, not only on an online estimate.
Provider comparison checklist
| Item | LESCO / FESCO / IESCO | K-Electric | Why it matters |
|---|---|---|---|
| Base tariff | Check the applicable notified DISCO schedule | Check K-Electric's applicable schedule | Schedules and effective dates may differ |
| Consumer status | Match category, load and protected status | Match category, load and protected status | Provider name is not enough |
| Adjustments | Check month and notification | Check month and notification | An adjustment may relate to an earlier period |
| Final verification | Provider bill plus NEPRA material | K-Electric bill plus NEPRA material | The actual account controls the comparison |
This table compares the checking process; it deliberately does not publish a permanent rupees-per-unit figure because notified rates and adjustments change.
Worked example: compare two 350-unit bills
Suppose two relatives each used 350 units, one in Lahore and one in Karachi. Their payable totals still cannot be compared fairly until the account category, protected history, billing days, load, taxes and adjustments are aligned.
- Write the base energy charge from each bill.
- Place fixed charges, taxes and every adjustment in separate rows.
- Remove arrears, late fees and account-specific credits from the consumption comparison.
- Divide the comparable subtotal by units and document remaining differences rather than assuming an error.
Frequently asked questions
Does every DISCO use exactly the same residential slab calculation?
Do not assume that from a generic table. Match the official schedule, category, status and effective date for the bill being checked.
Why is my effective per-unit rate higher than the advertised slab?
The payable total can include fixed charges, taxes, fuel or quarterly adjustments, arrears and other items beyond the base energy charge.
Is K-Electric always more expensive than LESCO?
That claim cannot be made from one bill. Usage, consumer status, month and account-specific items must be normalised first.
Can I compare bills using only units?
Units are essential, but billing days, category, status, load, taxes and adjustments are also needed.
Which amount should a calculator reproduce first?
Start with the base energy charge, then add each visible bill component separately so any difference remains explainable.
